Definitions

  • the present invention relates to a screw-nut device, intended to automatically take up a clearance, in which the screw is associated with a pusher capable of exerting on it an axial thrust which can cause its displacement, the thread of the screw having angles determined propeller and pressure.
  • the object of the invention is therefore to produce an automatic play take-up device, applicable not only to systems such as those mentioned above which relate to the automobile industry, but also to a very large number of other devices in other technical fields, by example of bicycles, motorcycles, etc.
  • the helix and pressure angles of the screw are chosen so that in a first direction known as reversible, the screw can, under the axial thrust exerted in this direction by an elastic member, perform a helical movement in the nut each time that the force exerted by the pusher disappears or is reduced sufficiently, and that in a second direction known as irreversible, opposite to the first, the screw acted upon by the pusher by an effort much greater than the effort of the elastic member in this second direction cannot perform either translation or rotation in the nut.
  • the pressure angles of the two sidewalls are different, one preferably being between zero and a low value, and the other pressure angle being high.
  • the pressure angle equal to 0 or small corresponds to the reversible direction of translation and rotation of the screw and therefore allows the play to be taken up by moving the screw in this direction, while the screw cannot move in the opposite direction. .
  • the side of the thread, the pressure angle of which is high, having a suitably chosen value prevents any backward movement of the screw when it is applied to the corresponding surface of the nut by the pusher.
  • FIG. 1 a screw 1 whose thread 2 is engaged in the corresponding tapping of a nut 3.
  • the thread 2 is inclined on the perpendicular to the axis XX of the screw 1 with a helix angle ⁇ .
  • the net 2 having a pitch p.
  • the friction coefficient f between two surfaces belonging to different objects is defined by the ratio between the force T ( Figures 3 and 4) necessary to slide the two surfaces relative to each other and directed along the direction of movement, and the force N, which is the pressing force applying the two surfaces one on the other.
  • the angle friction between the two surfaces is the angle between the resultant R of N and T ( Figure 4) and the force N.
  • the efficiency of the screw 1-nut 3 system in which the screw is subjected to an axial force F (Figure 1) is by definition, the ratio of the power obtained at the output by the power supplied at the input.
  • a force F is provided in the axis of the screw 1, which leads to a linear displacement of the latter and a torque C is recovered on the nut 3.
  • the tangential force exerted on the nut 3 being Ft, we show that the yield is defined by the expression below
  • r being the mean radius of the screw
  • the torque C is defined by the following relation and the tangential force is
  • the graph in FIG. 21 illustrates the evolution of the ratio Ft / F, that is to say of the efficiency ⁇ . as a function of the helix angle ⁇ plotted on the abscissa and the frottsment angle ⁇ .
  • the pressure angle 0 is the angle of inclination of the side of the thread 2 (surface on which the contact between the screw 1 and the nut 3 takes place) relative to the perpendicular to the axis XX of screw 1.
  • the invention provides that the helix ⁇ and pressure ⁇ angles are chosen so that in a first direction known as reversible S1, the screw 4 can under the axial thrust F exerted in this direction, effect a translation and a rotation in the nut. and that in a second direction S2 said to be irreversible, opposite to the first, the screw 4 undergoing an axial thrust in this second direction S2 cannot effect either translation or rotation in the nut.
  • the thread 5 has two sides 5a and 5b whose pressure angles are very different: the angle of preasion ⁇ 1 of the side 5a is very small (a few degrees) and may also be zero, while the pressure angle ⁇ 2 of the second flank 5b, oriented in the irreversible direction S2. is high.
  • the bearing surface is that of the flank 5b and the yield is:
  • the two above conditions for the efficiency ⁇ lead to the determination of an interval of values of the angle ⁇ , this interval depending on the value of ⁇ .
  • the upper limit value of ⁇ is the value of the wedging angle
  • the lower limit value of ⁇ is the value for which there is no helix angle ⁇ satisfying the two aforementioned conditions.
  • a coefficient of friction associated with a friction angle ⁇ 16.7 'is high and therefore corresponds to a significant friction between the surfaces. So if for such a coefficient of friction the reversibility is obtained in the direction considered, this reversibility will in any case be preserved if the state of the surfaces in contact deteriorates during operation of the device, as long as the coef f i-cient of friction tg ⁇ is less than 0.3.
  • Figure 20 shows the principle of a screw-nut device according to the invention, subjected to an alternating axial force in both directions, tolerating screwing in one of the two directions and prohibiting it in the other.
  • the screw 6, provided with a thread 7 satisfying the conditions explained above. is housed in a nut-body 8, and urged in the irreversible direction by a pusher 9 exerting on the screw 6 an axial force P, and in the opposite direction reversible by a helical spring 11 bearing on the bottom of the nut 8 .
  • each flank of the thread of the screw has its own pressure angle, the helix angle ⁇ being constant and greater than the friction angle ⁇ .
  • the invention can also be implemented by varying the angle of the helix ⁇ , the pitch p of the screw remaining constant as well as its angle of presslonl ⁇ .
  • two consecutive cavities of the thread 82 are separated by a projecting thread 83 in which, on the side of the tooth 19, is a recess 84 delimiting on the thread 83 a face 85 bearing the tooth 19 when the screw 22 is actuated in the reversible direction ( Figure 9).
  • This support on the face 85 corresponds to an average diameter d4 of the screw 22.
  • the reversible operating direction is that in which the screw 22 undergoes a pushing application of the teeth 18 against the radial faces 86 of the internal thread 82 opposite the faces 85 (FIG. 8).
  • the screw 90 is made up of two parts of different mean diameters d1 and d2 with d2> d1, the pitch p of the thread being constant.
  • the part of the thread corresponding to the diameter d2 therefore has a helix angle ⁇ 2 less than the helix angle ⁇ 1 of the part of diameter d1.
  • the teeth 91 of average diameter d1 are received in a thread 92 of the nut 93, and the teeth 94 of average diameter d2 are received in a complementary thread 95, the two end teeth 91 and 94 engaging in a housing 96 suitably machined in the nut 93.
  • the threads 92, May 9, 96 are dimensioned so as to be reserved for threads of the screw 90 a minimum operating clearance and recovery elastic strain as previously explained.
  • the invention provides to combine the previous embodiments to produce a screw having different pressure and helix angles depending on the direction of operation, the pitch p remaining the same in both directions of operation. reversible and irreversible. Such a combination makes it possible to increase the performance of the screw-nut system by reducing its size.
  • a flank 24 of the thread 25 of the screw 26 is profiled in staircase fashion by presenting a step 27 between the top 28 of the thread 25 and the surface 29 of the core of the screw 26, the pressure angles of the straight portions of the sidewall 24 located on either side of the step 27 being zero.
  • the second flank 31 of the screw 26 has an angle of high pressure ⁇ .
  • flank 24 is associated with the helix angle ⁇ 1 corresponding to the diameter d5 and flank 31 is associated with the helix angle corresponding to the diameter d6.
  • the thread of the nut 32 has a profile comprising a wall perpendicular to the axis of the screw 26, intended to come into contact with the portion of the sidewall 24 between the surface 29 and the step 27, and a wall 86 opposite flank 31 with the same inclination as the latter.
  • the thread is constituted in axial section by two teeth 33, 34 of unequal heights, the height of the tooth 34 being greater than that of the tooth 33 and the diameter of the screw being constant .
  • the flanks of tooth 33 have zero or practically zero pressure angles, as well as the flank 35 of tooth 34 turned towards tooth 33.
  • the second flank 36 is inclined on the perpendicular to the axis of the screw a high pressure angle (around 60 degrees in the example shown).
  • the associated nut includes a thread 37 receiving the two teeth 33, 34, with sufficient clearance, this thread 37 being delimited on the side of the tooth 33 by a radial wall 38 orthogonal to the axis of the screw and on the side of the inclined face 36 by a wall 39 of the same inclination.
  • An annular shoulder 41 delimited by the walls 38 and 39 penetrates with clearance between two consecutive teeth 34 and 33, and the latter have respectively average diameters d8 and d7 bearing against the associated walls.
  • Figure 13A differs from that of Figures 8A-9A in that the teeth 94 are replaced by teeth 97, the faces 98 of which face in the direction opposite to the teeth 91 have a high pressure angle, the other faces 99 of the teeth 97 maintaining a zero pressure angle.
  • the nut comprises, facing the thread formed by the teeth 97, threads 101 penetrating with play between two consecutive teeth 97 and whose walls 102 are parallel to the inclined faces 98.
  • the invention provides in such cases for achieving a low coefficient of friction on the side of the thread which works in the reversible direction, and on the other hand a high coefficient of friction on the side of the thread which works in the direction irreversible.

  • the screw 45 is made of a material harder than that of the nut 46, so that the grooves 51 penetrate into the corresponding flank of the thread of the nut and that there is thus interference of material between the screw 45 and the nut 46.
  • the latter can also carry grooves compatible with the grooves 51 of the screw 45.
